A military conflict infobox (sometimes referred to as a warbox) may be used to summarize information about a particular military conflict (a battle, campaign, war, or group of related wars) in a standard manner.

Note: When using parameters, avoid the ambiguous abbreviation "N/A", and instead use "unknown" or "none". All subjective or qualitative judgements and numerical quantities or statistics must be cited to a reliable source (see WP:MILMOS#CITE).

conflict – the name of the conflict being described (e.g. "Battle of Lützen" or "World War I").

partof – optional – the larger conflict containing the event described in the article. For battles or campaigns, this should be the war during which the event takes place; for particularly large wars, this may include a theatre (e.g. "the Eastern Front of World War II"). For wars, the parameter may be used to link to a larger group of wars (e.g. the Italian War of 1521–26 to the Italian Wars). It may be necessary to insert "the" before the name of the war for proper grammar.

image – optional – an image for the warbox. The image must be given in the form [[Image:Example.jpg|300px|alt=Example alt text]]; in particular, the thumb attribute must not be selected.

caption – optional – the text to be placed below the image.

date – optional – the date of the conflict described. Convention is to give the actual date for battles and the years for wars, but this does not always apply.

place – the location of the conflict. For conflicts covering a wide area, a general description (e.g. "France", or "Europe", or "Worldwide") may be used.

coordinates – optional – the location of the structure, given as a coordinate pair by using {{coord}} with display=inline,title.

map_type – optional – the base map to be used for the location map, e.g. "Scotland"; see {{location map}} for more details.

map_type – optional – "yes" if the location map is a relief map; see {{location map}} for more details.

map_label – optional – the label placed next to the marker on the location map.

territory – optional – any changes in territorial control as a result of the conflict; this should not be used for overly lengthy descriptions of the peace settlement.

result – optional – this parameter may use one of several standard terms: "X victory", "Decisive X victory" or "Inconclusive". The choice of term should reflect what the sources say. In cases where the standard terms do not accurately describe the outcome, a link to the section of the article where the result is discussed in detail (such as "See the 'Aftermath' section") should be used instead of introducing non-standard terms like "marginal" or "tactical" or contradictory statements like "decisive tactical victory but strategic defeat". It is better to omit this parameter altogether than to engage in speculation about which side won or by how much.

status – optional – for ongoing conflicts, the current status of the conflict. This should not be used if a final result (above) is provided.

combatant1/combatant2/combatant3 – optional – the parties participating in the conflict. This is most commonly the countries whose forces took part in the conflict; however, larger groups (such as alliances or international organizations) or smaller ones (such as particular units, formations, or groups) may be indicated if doing so improves reader understanding. When there is a large number of participants, it may be better to list only the three or four major groups on each side of the conflict, and to describe the rest in the body of the article. The combatant3 field may be used if a conflict has three distinct "sides", and should be left blank on other articles. Combatants should be listed in order of importance to the conflict, be it in terms of military contribution, political clout, or a recognized chain of command. If differing metrics can support alternative lists, then ordering is left to the editors of the particular article.

combatant1a/combatant2a/combatant3a – optional – in cases where the parties significantly changed over the course of the conflict, these subsidiary fields may be used to provide additional rows for the combatantN fields (above).

commander1/commander2/commander3 – optional – the commanders of the military forces involved. For battles, this should include military commanders (and other officers as necessary). For wars, only prominent or notable leaders should be listed, with an upper limit of about seven per combatant column recommended. Ranks and position titles should be omitted. The {{KIA}} and {{POW}} templates may be included immediately after the names of commanders who were killed in action or surrendered and were taken prisoner, respectively. The commander3 field can only be used if the combatant3 field is set.

units1/units2/units3 – optional – the units or formations involved. If a large number of distinct formations is present, it may be better to reference an order of battle in the body of the article than to include the entire list in this field. The units3 field can only be used if the combatant3 field is set.

strength3 – optional – if combatant3 is set, this is a third strength field identical to the two above; if it is not set, this is an alternate combined field for use where only the total participation in a conflict is known.

casualties1/casualties2 – optional – casualties suffered, including dead, wounded, missing, captured, and civilian deaths. Terms such as "dead" (or "killed"), "wounded", or "captured" should be used in place of abbreviations such as "KIA" or "POW".

casualties3 – optional – if combatant3 is set, this is a third casualty field identical to the two above; if it is not set, this is an alternate combined field for use where only the total casualties of a conflict are known, or where civilian casualties cannot be directly attributed to either side.

notes – optional – optional field for further notes; this should only be used in exceptional circumstances.

campaignbox – optional – optional field for appending a campaignbox template to the bottom of the infobox, which allows both boxes to float as a single element (useful if there are subsequent left floating images, which would otherwise not be able to float above the campaign box); the template must be specified in the format {{Campaignbox XYZ}}.

The HTML markup produced by this template includes an hCalendar microformat, which makes the event details parsable by computers, either acting automatically to catalogue article across Wikipedia, or via a browser tool operated by a person, to (for example) add the subject to a calendar or diary application. Within the hCalendar is a Geo microformat, which additionally makes the coordinates (latitude & longitude) parsable, so that they can be, say, looked up on a map, or downloaded to a GPS unit. For more information about the use of microformats on Wikipedia, please see the microformat project.
